According to Mega Millions website, lottery officials will verify early Saturday morning whether there are any winning tickets.

Millions of Americans who want to be multi-millionaires had been holding their collective breath to see whether the number they have selected for the largest lottery jackpot would win them a whopping $640-million prize.

If no winner claims the winning number Friday night then the lottery money will be increased to $975 million for next Tuesday's draw.

The jackpot has been growing since Jan. 24, and has rolled 18 times without a winner. However, earlier today the jackpot price shot up from $540 million to $640 million.

The previous jackpot was in March 2007 with a record amount of $390 million. However, the money was later divided between two winners who purchased tickets in Georgia and New Jersey.

The winner will have two options to take the jackpot home. The first is to take the immediate cash which will come up to $462 million after deducting taxes and the other option is to take the full amount annually for over a period of 26 years.

The six-month grace period for many student loans is about to expire for new college graduates. If the past is any guide, many people will miss their first payment and some will end up defaulting on their loans - even though there's usually no good reason for that to happen.
